New Valves for Croft Integrated - but which....

I am the lucky owner of one of Glenn's Integrated amps.

It has been upgraded to an active pre-amp as well as an improved power supply.

Currently running RCA 12BH7 and Sovtek 12AX-LPS valves but I'm looking to change things up a bit and was wondering what recommendations you may have?

Brimar 12BH7 - darker and meatier than the RCA which is a favourite of mine by the way in that position.

Tesla ECC83 NOS in the phono stage. Crystal clear with insight and great resolution.

Glenn is fond of modern JJ's. I've got PSvane's in my RIAA and it sounds sublime :)

Said it before... 1950s Tungsram ECC83 foil getters, not heard anything that comes close.

Of the 4 NOS tubes ive tried so far ,including sylvania ,mullard and EH, the 1956 RCA black plate 12bh7A are the best by some margin.
